An exploratory persistent-homology analysis of resting-state fMRI functional connectivity under Ayahuasca

This exploratory brain imaging study (n=9) examined resting-state fMRI connectivity before and after ayahuasca and found a small drop in one measure of topological complexity in the main analysis, but this did not hold up after correction and was not seen when signed correlations were used. Exploratory measures of signal complexity rose slightly but not significantly.
